3%, 29 years HIVST vs. 48.7%, 27 years standard HTS). In total, 34 (3.9%) reactive results were reported from 938 people with known HIVST results; 32.4% were males, and median age was 30 years (interquartile range 25-36). Twenty-one (62%) patients were known to have received confirmatory blood-based HTS; of these, 20 (95%) had concordant reactive results and 19 (95%) were linked to HIV care at a clinic. CONCLUSION Integration of HIVST into existing HIV facility and community-based testing strategies in Eswatini was found to be feasible, and HIVST has been adopted by national testing bodies in Eswatini.

Yet current understanding of historical changes to lagoon ecosystems is still poor due to the extensive labor requirements and expense of quantitative analyses. In this issue, Hapsari and colleagues analyze a unique data set that reconstructs the environmental change and carbon dynamics of the past 400 years for a tropical mangrove-fringed lagoon system in Java, Indonesia. Their work provides important insights into how climate change and human land use co-regulate the vegetation and carbon cycles of a tropical lagoon system and its catchment.

Certain bacteria adapt by means of cellular differentiation, resulting in the development of a specific cell type that is specialized for life in a distinct environment. Furthermore, to understand how bacteria adapt, it is essential to appreciate the significant changes that occur at the proteomic level. By analysing the proteome of our model organism Vibrio parahaemolyticus from distinct environmental conditions and cellular differential states, we demonstrate that the proteomic expression profile is highly flexible, which likely allows it to adapt to life in different environmental conditions and habitats. We show that, even within the same swarm colony, there are specific zones of cells with distinct expression profiles. Furthermore, our data indicate that cell surface attachment and swarmer cell differentiation are distinct programmes that require specific proteomic expression profiles. This likely allows V. parahaemolyticus to adapt to life in different environmental conditions and habitats. Finally, our analyses reveal that the expression profile of the essential protein pool is highly fluid, with significant fluctuations that dependent on the specific life-style, environment and differentiation state of the bacterium. © 2020 The Authors.

We conducted a systematic review of the association between hearing loss and mental health conditions in low-and middle-income countries (LMICs). METHODS We searched six electronic databases using predetermined criteria to retrieve original research reporting mental health in people with hearing loss. We considered quantitative studies measuring any type of mental health conditions according to the ICD10 classifications of "Mental and behavioural disorders" in relation to any measure of hearing loss. We assessed risk of bias using a set of criteria according to the SIGN50 guidelines. RESULTS We included 12 studies evaluating 35,604 people with hearing loss in 10 countries. Poorer mental health (measured as (stress and anxiety, depression, and/or behavioural and emotional disorders) was more common among people with hearing loss compared to those without in 10 studies. One study found no difference in mental health outcomes between people with hearing, visual and no impairment. Another study reported that after hearing aids, those with severe hearing loss had significant improvement in psychosocial function, compared to no change among those without hearing loss. Overall, one study was judged to be high quality, 7 medium quality and 4 low quality. CONCLUSIONS Included studies showed a trend towards poorer mental health outcomes for people with hearing loss than for those without. However, our findings indicate that very few high-quality studies have been conducted in LMICs. This article is protected by copyright.

METHODS AND RESULTS The diversity of the microbiota of the sausages were studied using the Illumina HiSeq platform. The results showed that compared with the highest diversity of fermented bacteria in Guangdong, the bacterial diversity of fermented sausage was the lowest in Sichuan. The percentage of dominant phylum (Firmicutes, Cyanophyta, Proteobacter) were 78.39%, 13.13% and 7.14% in SC, 35.47%, 30.36% and 28.04% in GD, 54.81%, 28.91% and 14.00% in HN, 20.20%, 58.16% and 17.31% in HB, respectively. The dominant genus distribution of fermented sausages in different regions is regions varied, however lactic acid bacteria and cyanobacteria were dominant overall. Traditional fermented sausages using natural fermentation methods have poor microbiological safety, and pathogenic and spoilage microorganisms such as Acinetobacter, Brochothrix and Pseudomonas have been detected in all four regions. CONCLUSIONS The results in this paper provide a microbiota profile of four typical fermented sausages in China. There is a big difference in the microbiota of sausages in different regions, and the good flavor of traditional Chinese fermented sausage is related closely with the abundant microbial resources, however, the natural fermentation method also expose to the product security threats, including spoilage, pathogenic microorganisms and biogenic amines, etc. SIGNIFICANCE AND IMPACT OF THE STUDY The results would offer guidance for industrial fermented sausage production with certain flavor and also improve the microbial resource utilization, and contribute to the control of harmful microorganisms in traditional fermented sausage.
